## What is first angle method?

First angle projection is one of the methods used for orthographic projection drawings and is approved internationally except the United States. In this projection method, the object is placed in the first quadrant and is positioned in front of the vertical plane and above the horizontal plane.

**Which statement is correct for first angle projection?**

Explanation: In first angle projection the object’s right side will be projected only if we watch from right side of object and the impression will fall to the left side of front view similar to the other side also so the right side view is placed on the left side of front view.

### Where does 1st angle projection place the right view?

**What is 1st angle and 3rd angle method?**

In third-angle projection, the view of a component is drawn next to where the view was taken. In first-angle projection, the view is drawn on the other end of the component, at the opposite end from where the view was taken.

## What is a 3D oblique drawing?

Oblique projection is a simple type of technical drawing of graphical projection used for producing two-dimensional (2D) images of three-dimensional (3D) objects. Oblique projection is commonly used in technical drawing.

**Which is an example of first angle projection?**

In first-angle projection, each view is shown as if the viewer is looking through the object and projecting the image on the other side. This style is the most common one used in Europe. Here is an example of first-angle projection (see video). The red arrows represent the view of the observer with the image being projected on the other side.

### Who was the first mathematician to do perspective drawing?

A modern deductive footing for perspective drawing was given later by Brook Taylor (1685-1731) and J. H. Lambert (1728-77). A competing point of view has held by mathematicians such as René Decartes (1596-1650), Pierre de Fermat (1601-1665) and Julius Plücker (1801-1868)…

**How to draw an acute triangle using a protractor?**

Draw two acute angles on your paper. Construct a third angle with a measure equal to the sum of the measures of the first two angles. Remember, you cannot use a protractor—use a compass and a straightedge only. 7. Draw a large acute triangle on the top half of your paper. Duplicate it on the bottom half, using your compass and straightedge.

## Which is a way of drawing an object from different directions?

Orthographic Projection is a way of drawing an 3D object from different directions. Usually a front, side and plan view are drawn so that a person looking at the drawing can see all the important sides.
